Grimoire

Summary

• New to version 0.3.x: grim_memory and page_memory
  • grim_memory: high-level local persistent context (until nil or shutdown)
  • page_memory: block-level local temporary context (until overrided)
• Override Grimoire's on-callbacks with files named "page_*.lua"
  • Apply with the chat command: /grimoire page <name of page>
• Single-use scripts are called from files named "invoke_*.lua"
  • Execute invoke files with /grimoire invoke <name of file>

Runtime Modifiable

Mod files can be edited or introduced during runtime without restarting Minetest.

The files within the pages folder are prefixed with either 'page_' or 'invoke_'.

Files named pages_ contain overriding callback methods used by the spellbook item.

Files named invoke_ contain functions to execute with the invoke chat command.

Grimoire Pages

The item grimoire:spellbook does nothing by default.

To use the spellbook, first use the chat command: /grimoire page builder.

This will select the file named page_builder.lua and will override the book's existing functions.

When a new page is added, or an existing page is modified, the page command can be used to apply the new functions.

You can use any callback functions such as on_use, on_place, on_secondary, on_drop, in combination with player controls (if they have been included in the function): up, down, left, right, jump, aux1, sneak, dig, place, LMB, RMB, and zoom.

• Dropping and placing the spellbook won't drop or place the book

• The book is destroyed if it is used by a player without the server privilege

• Available pages:

  • builder place and dig nodes
  • meta set owner to node
  • example various functional examples
  • template functionless template
  • disable disables Grimoire functions

Grimoire Invoke

Similar to pages, the invoke command will execute functions from file.

For example: /grimoire invoke echo will execute the function within invoke_echo.lua.

The functions will run only from chat command, and not added to the spellbook's functionality.

The invoke files can be modified and run again using the same command.

To add a new invoke command, a new file can be created from the invoke_template.lua template.

• Available invoke files:
  • echo sends chat message of command parameter
  • vanish make yourself disappear
  • memory basic grimoire context manager
  • formspec opens a formspec with parameter label
  • template functionless template

Grimoire Memory

The init.lua file contains a table grim_memory which is passed as a variable to pages or commands.

Using a new page or invoke command will not erase the grim_memory.

Each Grimoire page file can have a table for storing temporary variables to be used by the spellbook.

The page_memory table will be forgotten when a new page is selected.
